Title: Production of zn-mg vapor deposition-coated steel sheet
Inventor: SAKAMOTO KAZUYUKI
IPC: C23C14/58
Filed: 1994-03-29
Abstract: PURPOSE:To obtain a highly corrosion-resistant Zn-Mg alloy vapor deposition- coated steel sheet having a highly adhesive plating layer by suppressing the remaining of pure Mg and its alloying with the substrate steel. CONSTITUTION:A continuously traveled steel strip is introduced into a vacuum chamber, Mg is vapor-deposited on the steel strip kept at >=100 deg.C in a vacuum of 1X10<-6>-8X10<-4>Torr H2O partial pressure, then Zn is deposited, and the steel strip just after leaving the vacuum chamber is heat-treated at 250-370 deg.C in an inert atmosphere or in the atmosphere so that the diffusion reaction between Mg and Zn proceeds until pure Mg is not left. The Zn-plated steel strip is held at 130-250 deg.C for >=1hr in a nonoxidizing atmosphere by using a heating furnace independent of the vacuum chamber to apply alloying heat treatment. Otherwise, the steel strip is kept at >=100 deg.C before Mg vapor deposition, the temp. is controlled so that the Zn-deposited steel strip is kept at 250-370 deg.C, and the alloying heat treatment is conducted by the sensible heat of the strip.

Abstract: PURPOSE:To decrease insertion loss, to increase a block area attenuation and to attain small-size by using a seal agent to seal a cap made of a piezoelectric crystal being the same raw material as that of the chip, to a face on which an interdigital transducer of a chip is provided. CONSTITUTION:The face 10 where interdigital transducers 12, 13 on the piezoelectric crystal chip 10 are provided is sealed closely by the cap 11 made of the same raw material as that of the piezoelectric crystal chip 10. Thus, distortion due to a difference from a linear expansion coefficient is not caused and no air-tight package is required, then floating inductance and floating capacitance are reduced, and the characteristic is not deteriorated even at a high frequency (1GHz or over). Since air-tight sealing is applied, secular change is small. Since only the same area as that of the chip made of the piezoelectric crystal is required, a considerable miniaturization can be attained.
